Wales has produced a number of manuscripts over the centuries. Although most were written in Middle Welsh or Old Welsh, some were also written in Latin. In some of the more recent manuscripts it is not uncommon to have texts in Welsh, Latin, French and English in the same volume. However, some of the most important medieval manuscripts were written in Latin only, e.g. the Cyfraith Hywel.
There are several compilations of Welsh manuscripts. The most important, from a Welsh-language literature standpoint, are:
